The influence of silanes on the reaction of enones with cuprates has been examined using the title enone compound and Me2CuLi.LiI. In ether solvent the effect the effect of various silanes on the 1,4/1,2 addition ratio was minor. In tetrahydrofuran significantly increased 1,4/1,2 addition ratios and increased conversion of substrate was noted in the presence of silanes. Me3SiC1 proved to be the most
使用标题烯酮化合物和Me 2 CuLi.LiI检验了硅烷对烯酮与铜酸盐反应的影响。在醚溶剂中,各种硅烷对1,4 / 1,2添加比例的影响很小。在四氢呋喃中,在存在硅烷的情况下,显着提高了1,4 / 1,2的添加比例,并提高了底物的转化率。在优先添加1,4烯酮中,Me 3 SiC1被证明是最有效的硅烷。
